I've been running a Kodak OG5.6 KW (MKS IV) with a Pylontech UP5000 for a few months now, and zero issues.

Today, I plugged in a new UP5000, which I plan to run in parallel with the existing one.

The weird thing is that after 5 minutes of charging my new battery at high current (50A), my inverter changed it's "max charge" setting (02) to 20A, and I am unable to change it back. On the control panel, it appears happy to accept my previous max charge current (50A), but this has no effect, and when I go back in a 2nd time to alter that setting, it's back at 20A. I'm unable to make it higher or lower - it's locked at 20A.

I'm using the BMS cable, and it's on the Pylontech program setting.

Has anybody else seen this?

I'm hoping that if I make my original battery the master, then sanity will be restored... but this is really odd.

OK.. interesting update. I've now plugged the batteries in parallel, and used my original UP5000 as master. Now my max charge current is fixed at 40A.

The Pylontech will throttle charging as the SoC rises, in order to have more time to do cell balancing. There are also other states that will limit charge current - like temperature etc., but this is probably for balancing.

Thanks @P1000, that makes sense.

I'm thinking now that it's likely that it was always present, but I just never noticed it before.

Also, I saw that as the charge percentage neared 100%, the "02" setting went down further.

It may be that the new battery module needs a little time to balance the new cells. Once that is achieved, you may find that you're roughly at double the charge current you were at for one battery module.

Yes.. you guys are right.

This morning the max charge amps are 100.

Hi there

does anyone know the settings between Kodak 7.2 OG Inverter and Pylontech UP 5000 battery.
